The reason why this happened was because, (in addition to the caching system already offered by VRocker's hosting service), a recent decision was made to also get us onto CloudFlare so that users would have faster access to the website worldwide. As a result, CloudFlare's DNS servers accidentally exploited a bug in PHPBB3 regarding getting a user's IP address. Thankfully a fix was made available!
Courtesy of this user's blog, said fix was applied and tested, and appears to be working without any issues so far. To those who noticed the original IP address bug before, you should be happy to know that it is now gone.
Have a great day everyone!
